IMPRCVEMENT IN RELlSHlNG-MACHINES FOR TENONING SIASH.

The Schedule referredto ln these Letters Patent and making part of the iseme.

To all lwhom it may conce-rua Be it known that we, GEORGE L. SULLivAN `and EDWARD LIBPLNCOTT, ofGhicagoJn the county of Cook and State of Illinois, have invented a new and useful Relishing-Maehine; and we do hereby declare the following to be a full, cleai', and exact description thereof, which will enable others skilled in the art to which our invention appertaiiis to make and use the saine, reference being had to the accompanying drawing forming part of this specilicatioin Figure 1, Sheet I, is a transverse vertical section of our improved relishiiig-niachine taken in the line .r x, fig. 3. v

Figure 2, Sheet I, is a similar view with the relishing-saws removed.

Figure 3, Sheet I ,'is a transverse vertical section of" the saine, taken in the line i/ y, iig. 1.

Figure 4Slieet I, is an elevation of an adjustable box, forming the bearing for the pitman of the vertical saws.

- Figure 5, Sheet 1I, is a plan view ofthe table oi' the machine. A

Figures 6 and 7, SheetI II, are perspective views of door-rails, to be hereinafter referred to.

Similar letters of reference indicate corresponding parts in the vertical figures of the drawing.

This invention has for its object to provide iii'i proved iiieansforrelishing the tenons of sash, doei', and bliiidrails; and

It consist-s, primarily, in the arrangement of transversely-reciproeating saws ot' peculiar construction, with a series 'of vertically-reeiprocating saws, for the purpose of relishiiig the tenen of a rail at one operation.

It consists, further, in the iiieans for adjusting the vertically-reeiproeating and the relishing-saws, to regulate the size of the teiioii and relish.-

It consists, liiially, iii throwing the ielisliiiigsaws into operation, iiitermittiiigly, during the continual movement of the ripping-saus, aiidiii the combination of parts of the machine, :is will be hereinafter more fully described.

A is the fraiiie of the. iiiaeliine, supporting thc operating parts.

It is qiiadraiigular in shape, and provided with a hinged top, B, carrying the adjustable guide-traine U.

I) l) I) are three saws, arranged parallel to each gther, and working vertically through slots iii the table rIlieir lower ends are clamped within the cross-head E, atiixcd to the operating shank F in any suitable manner, and are driven from the crank-shaftG, having its bearings in the lower part of the frame, through the medium of the pitman II and shank F.

The guide-boxes, F', for the shank F, are arranged upon the cross bars I of the frame, as will be presently described.

J J are the cross-eut or relishing-saws, composed of metal plates, with the saw-teeth formed upon Atheir upper ends instead of upon the sides or edges. These saws are placed a short distance from each other iu front of the saws D, and are adapted for operation in following manner:

Their lower ends are attached to a guide-bar, K, capable of longitudinal movement, upon a second guidefraine, L, the latter being arranged for vertical move nient upon metal brackets M M, atfixed to the crossbars I of the frame, one upon each sideof the boxes F', as shown in fig. l.

Reciprocating motion is imparted to the guide-bai' K, for the purpose of moving the relishing-saws transversc] y of the frame, by means of the shaft N aixed to the under side of the table B, as shown, and 'the pitman O.

llie inner end ofthe shaft N is provided with a disk, I, through which is formed, dianietrically, a groove, containing the adjustable wrist-pin block Q, to which the pitman O is attached.

By adj ustiiig the block Q, through the inediiiiii of the slot and setserew It, as shown, the transverse movement or stroke of the relishing-saws is regulated.

'lhe bar K is guided in its movements between the beveled lugs S formed upon thc guide-frame L, and the relishiiig-saws are adjusted, with relation to each other,-by the slots formed in said bar and the setserews iii the ends of the saine. Motion is communicated tothe shaft N by beltiiig upon the niaiii drivingsha-ft G.

',lhe operation is :is follows:

'.Ihe .sash or door-rail to be relishcd, having first been teiioiicd at its ends, as shown atl), iig. 6, is laid upon the table Il, against the guide-frame C, with one of the tciioiis toward the saws D. It is then forced against the saws'which fornithe korf, shown by dotted lines, fig. 6, extendiiigi'o the shoulder c of the tenon. It is then withdrawn from the saws, and the shoulder of the tenon placed against a stop, T, resting loosely7 within the table Il, between thc i'elishiiig-saws. The relishingsaws are then proj ectcd through the table, by depressing the treadle U, arranged at the bottoni of the fraaie, and connected to the guide-frame L by the rod W, when the ielishing-saws,reciprocating transversely of the franie, as previously described, relish orcut out the poitioiis l of the teiioii, leaving the latter in the forni shown in tig. 7.

rllhe width of the relish or distance between the saws I) is adjusted by means of the loose blocks j' and setserews y in the cross-head Il, andthe transverse cut of the saws J is adjusted to conform to the/width ofthe relishes by the slots and set-screws in the guide-bar K, previously mentioned.

X is a springsdog, secured, at one end, to the top of the 'guide-frame L, with its 'free end, ii, immediately beneath the loose stop T, so that, when the guide-trame is moved up, by depressing the treadle U, it shall raise the stop sufficiently above the table to form a rest for the shoulder of the tenen. The stop is thrown up its whole length before the relishing-saws begin to cut.

This arrangement is necessary, as the rail to be relshed must move over thc stop when it is fed tothe saws D, and rest against the same while being operated upon by thc saws J. As thc--saws D move at a high rate otl speed, the guide-boxes of thc shank F are liable to become worn, and cause the same to vibrate to such an extent as to render its operation'very imperfect and unreliable.

To compensate for this wear vwit-hout supplying new boxes, we constructan adjustable box, which canbc tightened or loosened upon the shank, at pleasure. It is composed of two halves Y Y', which, when secured 'together bythe bolt 1', form a hexagonal opening for the passage ofthe shank F, of' similar form transversely.

The plates Z Z of the box are slotted, as shown at j, for the passage of screws, by which the box is attached to cross-bars of' the frame, this method of attachment permitting the ready adjustment of the box upon the shank.

Our improved machine can be easily converted into a scroll-saw, by removing the two outer saws of' the series D, and throwing off tho belt by which motion is connected to the cross-cut saws. The outer saws are removed by loosening thc set-screwsin the cross-head.

Having thus described our invention, n

What we claim new, and desire to secure by Letters latent, is p l. In a relishuig-i'naehine, the arrangement of transversely-reciprocating saws with vertically-rceiprocating saws, substantially as described, for the purpose specilied.

2. 'lhc ,series ot vertically-reeiprocating saws .1), adapted for adjust-meut, with relation to each other, within the cross-head E, by means of the blocks f and set-screws y, substantially as described.

3. A series of cross-cut saws, J, adapted for adjustment, with relation t-o each other, to regulate the Width of the relish in the tenon of a sash, door, or blind-rail, substantially as herein described.`

4. The combinationof the movable stop T with the relishing-saws J, for the purpose spccilied.

` 5. A relishing-machinefor the tenons of sash, door, and blind-rails, in which the relishing-saws are thrown into operation intermittingly during the continued movement of the ripping-saws, for thc purpose specilied.
